Intel® Xeon™ 6740E

The Intel Xeon 6740E is a server processor with 96 cores and 96 threads, built on the Sierra Forest architecture (Intel 3 process). It launched in Apr 2024. Clocks run from 2.4 GHz base to 3.2 GHz boost. A 96-MB L3 cache backs the cores (1.0 MB per core). It addresses DDR5 memory up to 4 GB across 8 channels. The chip drops into the FCLGA4710 socket and exposes PCIe 5.0 (88 lanes). Rated TDP is 250 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon 6740E scores 1,997 in single-core performance and 76,167 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,333 for overall performance, 52,304 for productivity performance, 45,486 for creator performance, 106,634 for engineering performance and 25,033 for gaming performance. Its multi-core throughput works out to 793 per core, 793 per thread and 305 per watt. Its computed efficiency index is 780. Its performance index is 153, so its overall performance is 53% above the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Xeon 6740E scores 457,614 in integer math, 309,333 in floating-point math, 1,786,845 in compression, 137,106 in cryptography, 7,608 in physics simulation, 78,968 in vector SIMD, 526 in the prime sieve and 220,684 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 677% above in integer math, 574% above in floating-point math, 684% above in compression, 1,093% above in cryptography, 598% above in physics simulation, 409% above in vector SIMD, 685% above in the prime sieve and 874% above in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Xeon 6740E has 96 physical cores and runs 96 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.40 GHz and boosts up to 3.20 GHz.

The Intel Xeon 6740E is a server processor, belongs to the Intel Xeon 6 family, uses the Sierra Forest architecture, carries the codename Sierra Forest and is manufactured on a Intel 3 process. It launched in Apr 2024.

The Intel Xeon 6740E has 96 MB of L3 cache. That adds up to about 96.0 MB of cache, or 1.00 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon 6740E supports DDR5 memory, addresses up to 4 GB of memory and uses 8 memory channels. It does not support DDR4 and LPDDR memory. It supports ECC memory.

The Intel Xeon 6740E does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon 6740E uses the FCLGA4710 socket, supports PCI Express 5.0 and provides up to 88 PCIe lanes.

The Intel Xeon 6740E has a rated TDP of 250 W.
